Hello, everyone. I have just bought a 1972 Type 2 Westfalia. I was just wondering if anyone has any idea why my inlet manifolds have the plugs/connectors that they do.
I have a 1700cc engine that has been bored out to 1800cc with twin 34 ICT Weber carburettors and a CB Performance linkage/manifold kit that I believe was also used with the previously installed Dellortos.
I believe that this is the kit that is installed:
http://www.cbperformance.com/ProductDetails.asp?ProductCode=6429
The installation instructions describe the rear port on each inlet manifold as having a 1/8" barbed connector and the front port as having a 1/8" pipe plug. The balance tube is supposed to be joined to the barbed connector on each inlet manifold.
My balance tube was disconnected. When I tried to reconnect it, I found that my set up appears to have a barbed connector on the left rear port and a pipe plug on the right rear port. This stopped me from connecting the tube to the right rear port. The front ports have two other types of connectors that were both capped off. Here are some photographs:
LEFT INLET MANIFOLD WITH BALANCE TUBE CONNECTED TO BARBED CONNECTOR & CAPPED OFF FRONT PORT
RIGHT INLET MANIFOLD WITH PIPE PLUG & CAPPED OFF FRONT PORT
RIGHT INLET MANIFOLD WITH FRONT PORT UNCAPPED
Does anybody have any idea why the inlet manifolds would be set up in this way? In particular, what would the connectors in the front ports be used for? |

so you can run the balance tube where you want to. IOW, it's a good design feature. _________________ It's just advice, do whatever you want with it!

You don't need no balance tube
I personally prefer parts like this, it's easier to put fittings where you need them. Not all engines are the same so it is nice that they are versatile. |
Lol well I won't be using nitrous or water injection anytime soon! I also have electronic ignition.
I think I do need the balance tube, if only for my brake servo as it tees off the balance tube between the carbs:
I suppose my question really is, why would someone install that fitting at the front of the inlet manifold? Does it serve the same purpose as a barbed fitting? |

That fitting in the right manifold looks like a quick-connect for an air hose! _________________ "Just $99 down and $64 a month for 36 months buys you a brand new Volkswagen Beetle!"

That's an interesting idea about the air hose connector. Why would they install an air hose connector on the inlet manifold?
I was mistaken before when I stated that the left rear inlet manifold had a barbed connector. I don't know why I thought that. I have taken a photograph today showing that both connectors on the left manifold are these weird shapes as well. This means that the person who did this changed all of the connectors from barbed unions to these weird shapes. Does anybody have any idea why they would do this?!
You can see on the original kit, that it should come with barbed connectors:

the same reason they have that high tech vacuum tee on the engine case.
Because they had them lying around! _________________ It's just advice, do whatever you want with it!

Yeah those are quick connects normally seen on air lines (for air tools and such). As John said the person prob just had them laying around... |

I believe those were for the A.I.R lines for the smog pump on California models. _________________ '57 oval window deluxe,Agave green(L240) 2276cc w/51.5 IDA's

I'm 100% sure they're quick connect fittings... Google it |

Thanks guys. I'm going to just use them anyway and I'll change them to barbed fittings one of the days. Do you think that they will seal OK if I just attach the balance tube to those weird connectors with jubilee clips? |

I know that. I meant the manifolds with the place for fittings. _________________ '57 oval window deluxe,Agave green(L240) 2276cc w/51.5 IDA's
